DESCRIPTION
The ALTEC 1590E Power Amplifier is designed for applications where
uninterrupted operation is a requisite. The 1590E provides 200 watts of
power at less than 1% total harmonic distortion (THD) from 50 Hz to 12
kHz, and has a frequency response of ±1 dB from 20 Hz to 20 kHz at one
watt output. Output transformer taps provide connections for 70.7-,
100-, 140- and 200-volt line distribution systems.
The 1590E features silicon solid-state circuitry, a switchable
high-pass filter for use in speech systems, input connections for
high-impedance

devices and for
150/600-ohm or 15,000-ohm balanced inputs, fail-safe protection for
output transistors, and a hinged front panel for rapid access to the
chassis interior.
The 1590E is capable of operation from a 120V or 240V ac source or
a negative grounded 28V dc source. The 1590E is UL listed for use in
commercial audio systems and fire protective signaling systems.
Designed for rack-mounted use, the 1590E occupies six units of vertical space (10 1/2").

Picking up where our SWA1501 leaves off, the Mackie
SWA1801 ups the ante with even more wattage and a bigger 18" transducer.
The SWA1801 features an internal 800-Watt FR (Fast Recovery) Series
amplifier and a high-precision 18" transducer custom designed for
optimal performance with the amp and enclosure. Onboard Mackie Active
electronics ensure seamless integration of the amplifier and transducer
at all times, creating a system that is highly efficient and versatile.
Add it all up and this high-output system will peel the paint right off
the walls!

TRUE MACKIE ACTIVE DESIGN
Active doesn't just mean the SWA1801 has an amplifier
bolted on its back — it means optimized electronics that provide
complete control and maximum performance over all components. The
onboard Active system controls the crossover filters, equalization,
protection for the transducer and electronics, and provides real time
vigilance over the entire system. There is simply no way that you can
get this kind of full system functionality by strapping an amp on the
back of a passive speaker box.

NO NEED FOR AN EXTERNAL CROSSOVER
Connecting and setting up the SWA1801 is a breeze. It
accepts a stereo or mono line-level signal via female XLR input jacks.
Male XLR Thru jacks are provided for daisy-chaining the signal to
additional SWA1801 cabinets. The built-in crossover routes the high
frequency content to the high-pass output jacks, which can be used to
feed the inputs of full-range Active speakers, such as those in the
Mackie SAz Series, or an amplifier powering a pair of passive speakers. A
Subwoofer Level control lets you adjust the balance between the
subwoofer and the full-range speakers.

THE SECRET TO OUR POWER
The SWA1801's built-in amplifier, which produces 800
watts continuous power, sits on a massive heatsink, eliminating the need
for fans and dramatically extending life expectancy. A tremendous
benefit of having the amplifier inside the subwoofer enclosure is that
the SWA1801 functions as a complete system, optimizing acoustic,
electronic, and mechanical designs to achieve the highest level of
performance and value.

SOLID WOOD CONSTRUCTIONFor high-output loudspeakers, real wood just sounds
better—and it looks better, too! The SWA1801 enclosure is made of select
15mm Baltic birch plywood and finished in black splatter paint.
Carrying handles are integrated into each side for easy loading, and
casters are attached to the rear for transport. Since you will probably
want the full-range enclosure nearby, a pole mount receptacle is
strategically placed on top of the enclosure.
